The Puerto Rican Equation (1998) was intended to provoke questions about the effects of United States colonialism on Puerto Rico, and encourage dialogue. To that end, Sánchez invited a broad spectrum of artists in Puerto Rico, New York, Chicago, Albany, and New Jersey to participate in the exhibition and discussion forums. The artists who participated in the exhibition were: José R. Alicea, José Luis Cortés, Elizam Escobar, Anaida Hernández, Luis de Jesús, Lillian Mulero, Martín García Rivera, Gloria Rodríguez, Pepón Osorio, Rafael Rivera Rosa, Melquiades Rosario Sastre, and Bibiana Suárez. Juan Sánchez (b. 1954) is a painter, printmaker and professor of fine arts at Hunter College (New York City). In his youth, Sánchez was an artist and activist during the emergence of the Puerto Rican empowerment movement in New York in the 1960s and 1970s. Sánchez’s art work and curatorial projects address sociopolitical issues, such as Puerto Rican independence, freedom for political prisoners, and neocolonialism in the Americas. The catalogue and exhibition, The Puerto Rican Equation, was part of an effort by artists in the United States, Puerto Rico, and the Philippines to respond critically to the Centennial of the Spanish-American War of 1898.
